technical question about powers of attorney

[DonkeyHohtay]

Now, I appreciate the following scenario is unlikely to ever happen, but still. And for clarity, all parties involved are in Scotland.

DH and I have power of attorney for each other. Both health and financial. Organised, registered, shelved and hopefully never needed.

My parents are both mid 70s and have also decided they want to do the same. They are intending naming each other to have power of attorney, In addition, they are each naming me and my sister as "second choice" should Mum or Dad be too frail to take on the responsibility. Sister and I are happy with this.

So here's the hypothetical....say something happens to me and I'm really ill. DH invokes the power of attorney and starts making decisions on my behalf. The one of my parents gets ill too, and wants to appoint me and sister as guardian. Would that power of attorney pass on to DH? Or would it just be sister who had to deal with it all?

No your DH would not be Attorney to your parents
Your sister would act alone

I think your parents, or anyone, can appoint replacement attorneys to act on their behalf if any of their appointed attorneys can no longer act in their interests, it's all on the Gov.uk site.

Like I said, it's a very unlikely scenario. Sister and I are both in our 40s, fit and well.
